A patient who police say was being combative at St. Joseph's Medical Center was shot by an off-duty HPD officer this morning.

It happened on the 8th floor of the hospital. Staff members contacted two HPD officers working security there about the patient.

When the two officers got there, they got into an altercation with the patient.

"When the officers arrived, he then began struggling with the officers, attempting to injure the officers," HPD Spokesman Keese Smith said, "The officers initially deployed a Taser, and when that taser had no effect, his partner then discharged a duty weapon striking the suspect."

The patient is being treated at the ICU for a gunshot wound. The two officers are also being treated for their injuries. One has a concussion and the other, lacerations on his head.

Houston police and the Harris County DA are investigating, but at this point, police say the officer did nothing wrong.

Patients trying to get inside the emergency room for treatment at the time said they were turned away because of the chaos.
